Question

The largest possible sphere is carved out of a wooden a solid cube of side 7 cm .find the value of wood left

Answer 1

Given the largest side of cube as 7cm.
largest side of cube id diameter d =7
radius r =d/2
=7/2
=3.5
volume of the sphere = 4/3 πr3
= 4/3 *(22/7)*(3.5)3
= 4/3 *(22/7)*(3.5)*(3.5)*(3.5)
=179.66

volume of sphere is 179.66 cm3          

Answer 2

Answer:

Step-by-step explanation:

Let the large side of cube be 7

Then we know d=2r and d=a

So, r = 7/2=3.5

Volume of sphere 4/3♓r^3

4/3*22^7*(3.5)^3

539/3
